Racing Fuel Systems

Hello members!
I am looking for two different metering blocks;
One is stamped 4731, this for List 3300 & L3301.
The other 5127, this one for List 3255-1

I am not looking for universal or other versions, these two numbers only please.

I live in Sweden, but potential parts will be payed in USD and shipped within the USA.

Thanks for listening.
